The pinion R is engaged by a toothed segments, carried by a segment-lever S, pivoted to the frame at s and provided with a scale 8 along its lower edge.

The lever S is operated by an arm T, pivoted to the frame at tand provided with a roller which projects into the cam slot or groove 0, motion being transmitted to the segment-lever S from the arm T by a block U, sliding along the arm T and provided with a roller a, which bears against the under side of the segment-lever S. The said sliding block U also carries an index 11., which is arranged to move over the scale 3 thereby indicating the length in inches of staying material which will be fed into the hammer, this length being ad justably determined by moving the block U along the arm T.

The curved lever I is provided with a slot or opening 2' through which the strip of stayin g material is passed on its way from the paste-applying machine to the feed-rollers.

The hammer K carries a V-shaped shearblade V, which acts in connection with a stationary corresponding shear-blade V to cut the strip of staying material into suitable lengths as the hammer descends.

The operation of my machine is as follows: The end of the strip of staying material is passed through the opening 2' in the curved lever I and is inserted between the feed-rollers M and M far enough to give the latter a secure hold on the strip. Before a stay can be applied to a box corner the necessary length of strip must be fed into the grooves 7; in the head. To do this, the foot of the operator is applied to the treadle, thereby depressing the same and rotating the cam-disk G, which swings the curved lover I so as to bring the hammer K down toward the anvil. The foot of the operator being then removed from the treadle the latter is returned to its raised position by the spring F, which also rotates the cam-disk C backward and raises the hammer K, at the same time lifting the lever T and the segment-lever S, which rotates the yoke P and operates the feed-rollers M M, thus feeding a length of the stay-strip forward into the grooves 7c in the hammer. The box to be stayed is then placed upon the anvil L and the treadle pressed down, which causes the hammer to descend and brings the upper knife V past the lower knife V, whereby the length of strip necessary to form the box-stay is severed from the web, said stay being carried on down and applied to the box-corner with sufficient pressure to cause the stay to firmly adhere to said box-corner. During this downward movement of the hammer the segment-lever S also moves downward and rotates the yoke P backward, the pawls p slipping over the ratchet-wheel O and allowing the fced-rollers M M to remain stationary. O11 removing the foot from the treadle the hammer is raised and a new length of strip fed forward into the grooves in the hammer, thus preparing it for staying the next box'corner.

Instead of the lower feed-roller hereinbefore described I may employ a disk M Fig. I, having an angular or rounded edge which bears against the bottom of the groove in the upper feed-roller and presses against the central line of the strip, the pasted portions of said strip passing one 011 each side of the edges of the said disk M therebypreventing the feeding mechanism from being smeared with paste.

\Vhile I have shown the upper roller as provided with a spring-actuated axis, it is obvious that its axis may be made immovable so far as vertical movement is concerned, and the lower feed roller or disk may be forced toward the upper one by suitably-arranged springs.

In my construction the feeding mechanism is caused to bend the strip of staying material transversely, so that it will conform to the shape of the corner of the box to he stayed, whereby the disadvantages due to the clasticity of the strip causing it to pull loose from the box-corner while the paste is still wet are avoided. Furthermore, the strip is stilfer when bent and can be fed into the hammer with less danger of bending or crumpling than when fed flat.

IVhat I claim, and desire to secure by Letters Patent, is-

1. In a box-staying machine, a cam-disk having a cam-slot,a lever provided with means engaging the cam-slot, a hammer carried by the lever, a feeding mechanism, and means intermediate the feeding mechanism and camdisk, whereby the feeding mechanism is actuated, substantially as set forth.

2. In a box-staying machine, the combination, with an arm, and a sliding block adjustable on said arm, of a segment-lever actuated by said block, a feed mechanism operated by the segment-lever, and means for moving the arm, substantially as set forth.

I11 a box-staying machine, the combination, with an arm, and a sliding block adjustable on said arm, of a roller mounted in said block,a segment-lever against which the roller bears, a feed mechanism operated by the segment-lever, and means for moving the arm, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
